Multiple newline characters for a output

[Blameying]

Thanks for your work! It is tiny but useful and convenient.

I noticed that in the macro definition of log. It uses a '\n' in the format! macro, and then uses println! to write to stdout and writeln! to write to a file. Both of these macros automatically append a '\n'.

When I want to print lots of logs, it is a little inconvenient. But I'm not sure if that's a feature.
